ATTRNEYs Patented July 22, 1952 WINDOW -CONSTRUCTION Harold E. Graves,Jr., Akron, Ohio, assignor to Br-own Graves Company, Akron, Ohio, acorporation of Ohio This invention relates to casement windows of theslidin'ghinge type.

In my prior Patents No. 1,973,565 and No. 2,051,638 I have shown windowsof this type, and the'present'invention relates to improved featiirs inthe hardware employed on windows of the type shown in thesaid patents.

In the aforesaid windowsitlie swinging sashes are easily'in's'ertedorremoved by tiltin the sash tojengag or 'disengageup'per and lower,pronged, spring clips'which' carry the hinges, and which clips engage inchannels secured to the window frame. There is a tendency for rain waterto collect in the lower one of these channels and, therefore, a central,run-off slot 'hasbeen provided. It is one object of. the invention toimprovethe hardware, onthe lower" part of'the sash; with especialreference to the"drai age'features. Another object is'to simplifythe'manufacture and mounting of the hardware elements associated withthe lower sash. Other objects are to'improve the hardware in generaL'togive more posi-, tive engagement of the sash inits mounting, to providea smoother, more certain action, and to protect the wood of a windowsill against the effects of rain water."

These and other ends will'be apparentto'those skilled in the art, fromthe accompanying specification, as illustrated in the'drawingsin which:

Fig. 12 is a view in perspective of one form of channel member.

In the drawings, the main window frame is indicated by the numeral I,and the swinging casement by the numeral 2. In the structureillustrated,the swinging casement is flanked by two supplementary easements 3, whichare perman ently closed.

The swinging casement 2 is provided with facing strips 4 and 4', setin-and-iastened by screws 5"to the outer faces of the upper and lowerrails, respectively, of the casement. Referring to the lower part of thecasement, the facing strip 4 has, on the hinged end of the casement, anextension 6 which is bent downwardly. and again bent atits'end 8 intoparallelism with the lower edgeofthe basement. In the end -8 is secured,as by riveting. a pin 9 having a head -II, and around the pin 9 iswrapped a two-pronged leaf spring I2 (Fig. 6) having a short arm I3 anda long arm I4, the arms being bentinwardly at their ends to facilitatesliding of the spring.

The leaf spring is slidable in a, metal channel secured by a screw I5 ina groove H which is formed by routing the lower sill I8, the grooveextending beyond the hinged end of the easement 2, as at I9, toaccommodate the hinge pin 9, which is outboard withrespect tocasem'entl.

The upright side walls 20, 2 I of the channel extend from an end wall 22at the inner end of groove extension IQ for a distance slightly beyondthe center of the casement-,-at which location the bottom 23 of thechannel'is bent-upward to provide a vertical-wall 24 to the heightof thechannel and is then bent into parallelism with the bottom 23ofthechannel, to form a-facing' plate.

26. Beneath the latter is a strip of wood 2-1, which serves-as abacking, and both plate 26 and strip 21 aresecured to'the sill by ascrew IS. AS most clearly seen in Fig. 12, the channel a'ndfacing stripare formed froma single pieceofmaterial Plate 26 and woodenstripi'l-have aligned bores 28, 29, respectively, which receive,- andanchor,-a pin 3| which is secured inoneend of-a radius-rod 32, the otherend of which is pivoted to-the cen tral part of lower facing strip i ofthe casement, bymeans of arivet33.

A conventional latch 34 is provided on the'free end of theflcasement 2and it will be seenthat. as the casement is urged outwardly'by'apressureon its latching end, the. casementfisj constrained to turn aboutthe 'r'ivet33 and; ass. consequence;

the hinge pins 9 move toward the center of the sill, along the channel.Upon closing, the action wall 20, and the bottom of the channel wasdiagri onal at its end. This permitted run-off of rain water, but thetop of the sill, at the'outlet, was" exposed to the effects of the wateBy the present construction, theouter wall 2| of the channel is also theshorter Wall, but by the integral construction, the sill, at the run-01fpoint I for rain water, is covered by the channelbcttom',

this protective covering being extended to the outer edge of the sill bythe tab 36 (Fig. which is bent downward from wal12-i of the channel toprovide the water exit. 'Thi's'feature,together with; end 22 andriser 24provide complete. protection of all wooden surfaces on the sill top fromthe efiects of rain water. I Obviously, the'various joints-may besoldered or brazed. Furthermore, these; advantages arise from theunitary structureof-the channel and facing plate, which is, in itself, adesirable-feature in the matters of manufacture and assembly.

. The combined slidechannel and face plate in the upper part of thewindow frame is identical with the, loweronei except"v that the cuttingand bending of theftab (iii mayibe omitted,'.'sincethe problem ofwaterdrainage'is'not present.

The hinges and leaf springs aresomewhat dif-, ferent at the ,top and.bottom of the easement. Inall open positionsot the casement, its weightis almost entirely carried b'y the sliding hinge and theradius link 39,.To provide smooth sliding qualities, the weight at the. hingefislcarrie'd by the head i i. of the hinge pin 9, the lo'weredges of leafspring arias, l 3, I' lterminating above the head H for purpose."Another reason for thisoifset is the ifaict. that the o f the hingepinsmust be tilted in the act of inserting them in T the channels.Downwardly bent: extension :6 of the face plated compensates for thethicknessof radius link 32 and ensures that head ii of the hinge pinrestson the bottom atall times. I

Another consequence of the necessity for tilting the easement wheninserting it in place is that the upper hingepin does not contact thetop of its receiving channel. Therefore, the extension 55 of the upperfacing plate is straight. Since the upper hinge pin must occupy aposition somewhat downwardly of the top of its channel, the leaf springarms [3, l4" are fashioned so that their top edges are flush with thetop of pin head N. This ensures that the leaf spring arms lie within'thechannel to-provide maximum surface contacttherewith. v

In Fig. '7 is shown an prising the facing plate for the casement, theradius'link, and thesliding hinge It will be noted that the radius link32 has a natural, bowed form prior to mounting of the easement. Thisensures retention of the pins 3| in the window frame and also minimizesfriction between the radius link and the facing plate 5 to which it ispivoted. In order to increasethe strength and permanence of thespringfaction'of the bowed radius link, it is ribbed longitudinally atthe time the bow'is formed as at '36, so that its'lateral cross-sectionhas the form indicated inFig. 8'.

assembly of the unit com- In Figs. 9 and 10 is shown a modification ofthe combined, channel and face plate wherein the wooden backing strip 27may be eliminated. As best seen in Fig. 10, the facing portion 26 hasintegral, depending sides 37, 38 which serve to space it from the bottomof the groove in the sill, thus avoiding. the need for thewooden spacer.

While certain,preferrediforms of the device have been shown anddescribed, the invention is not limited thereby, since changes in thesize,

shape and arrangement, for instance, of various parts may be resortedto, without departing fromthe spirit or scope of the appended claims.
